SCAFFOLDING.

Specification of Letters Patent.

Patented June 22, 1915..

Application filed May 28, 1914. Serial No. 841,600.

To all whom it may concern:

Be it known that LLAZARUS G. HINNANT, citizen of the United States, residing at Spring Hope, in the county of Nash and State of North Carolina, have invented certain new and useful Improvements in Scaffolding, of which the following is a specification.

My invention relates to improvements 1n scaffolding, and as its primary object contemplates an adjustable and separable structure particularly adapted for exterior work.

The invention as a further object aims to provide a sectional scafiolding support, each section having means associated therewith whereby the several sections are locked and held in proper place.

As a still further object, the invention resides in the provision of means attachable to the top scaffold section and to the building, said means being adjustable and serving, when adjusted as a brace or fastening means for holding the entire scaffolding or struc ture immovable when in use.

As a further object of the invention I contemplate a scaffolding support comprising a series of superposable sections having means for holding them rigidly in line in superimposed relation and each comprising divergent boards braced across the angle by bars so that the succession of bars may serve as a ladder and maintain rigidly the angle between the boards while leaving the space between the free end of the boards unobstructed for entrance of the user to the ladder thus formed.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a perspective view illustrating the application of the present invention; and Fig. 2 is a perspective view, partly broken away, of one of the scaffold sections.

Referring now to the drawings by numerals, l designates as an entirety the scaffolding, the same comprising a plurality of scaffold sections 2, each section including a pair of boards 3 arranged end to end and at substantially right angles to each other as shown to advantage in Fig. 2. As a means whereby the boards 3 are held in place, I provide brackets 4, preferably three in number, arranged in spaced relation against the inner faces of the respective boards 3 as shown, the several brackets t being attached as at 5 and, when assembled, forming substantially square openings or spaces within which beams 6, square in cross section, are fitted. When assembling the scaffold sections, the said sections are placed one upon the other as shown in Fig. l, the beams 6 being of such length as to fit two of the bracketsof one section and one of the brackets of the next or adjacent section and, where two or more scaffold sections are used, the beams, as shown to advantage in the said figure, are so arranged relatively to each other as to rest one upon the other, end to end. By the above arrangement, it is apparent that the several scaffold sections are held immovable relatively to each other and in proper place one upon the other, thus permitting, by increasing or diminishing the number of sections, an increase or decrease in the height of the scaffold, the height being (determined by the nature of the work being one.

Serving as a brace for the board 3 of each section, I provide strips 7, said strips, when a plurality of scaffold sections are in use, also providing a means whereby the workmen may ascend and descend the scaffold, the said strips being utilized as ladder rungs or steps. Upon the outer face of the boards 3 of each section I secure brackets 8, one of the brackets being disposed to extend longitudinally of the boards and the other of the said brackets at an angle thereto or transversely of the boards as shown in said Fig. 1. Within one of the brackets 8 is fitted an angle iron 9, said iron forming a part of an arm 10 upon which the platform 11 rests, the angle iron being attached to the arm as shown at 12. Secured to the free end of the arm 10 in any suitable manner is a brace 14:, the inner end of which is provided with an extension 15 somewhat smaller in size than the brace to form a shoulder adapted for engagement with the angular-1y disposed brackets, the extensions 15 fitting the brackets, the latter serving as a support means therefor. Where a plurality of scaffold sections are used, the arms 10 and braces 1% are adapted to fit brackets 8 carried by the top section to in this manner support the platform 11 at the height desired, one of the longitudinal edges of the platform fitting against the side of the building or structure operated upon, the respective ends of the scaffold section 2 being in space relation to the building to provide a space whereby access to the interior of the scaffolding may be effected and the workmen permitted to ascend and descend the ladder formed by the strips 7 above noted.

As a means whereby the scaffolding, is

laterally braced, 1 provide guy ropes 15,

each rope having a tightening device 16 associated therewith. A hook 17 is formed upon one end of the rope 15, the hook being directly engageable with the structure operated upon, and, when placed as shown in Fig. 1, the opposite end of the rope being attached to the uppermost scaffold section, and the tightening device adjusted to draw the guy ropes taut, it is apparent that the entire scaffolding is braced and held in proper place.

From the foregoing, taken in connection with the accompanying drawings it is apparent that the scafi'olding may be 001- lapsed or separated to facilitate transportation; that any number of scaflolding sections may be utilized the scaffolding being built by adding sections to the desired height; and that by providing the supporting arms, the platform 11 isheld in proper place relatively to that surface of the building upon which the workmen is to operate.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my inventioii, as defined in the appended claim.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

A scaffolding including a support comprising a series of superposable sections having means for holding them rigidly in line in superimposed relation and each comprising two divergent boards braced across the angle by bars so that the succession of bars of superposed sections may serve as a ladder and maintain rigidly the angle be tween the boards while leaving the space between the free end of the boards unobstructed for entrance of the user to the ladder so formed;

In testimony whereof I ailix my signature in presence of two witnesses.
